Callum Gilden


Excelling at maths, physics and computer studies at high school was a clear sign that Callum was destined for a career in engineering. After studying engineering on his doorstep at Canterbury University, Callum now works in Pacific Commissioning’s South Island team.

Callum credits the breadth of Pacific Commissioning’s projects for the ability to work on a diverse range of projects. From health hubs to schools and university residences, no project is the same – except for the reward of knowing he’s played a role in something making a difference to a community or group of people.

Both output driven and an excellent communicator, Callum seamlessly balances a methodological approach of project planning and task management, with the people side of project management, across a broad range of stakeholders from sub-contractors through to commercial executives.

Rolleston is one of the country’s fastest growing areas and with its increase in population, the town’s only secondary school with a roll of 1400 students also needed to expand for a new generation of students. The new expansion caters to 700 new students and is a brand new state-of-the-art teaching block, including photography and robotics studios, art suites and a new gym extension, giving local families the confidence that their children have a purpose-built, modern space to support their learning. With a second campus planned for around two kilometres from the current college, it’s final capacity of 3,400 pupils will aim to make it the largest college in the country.
